除甲基共聚物外，还从草叶草秋叶中分离出迄今未知的3-acetoxylabda-8（20）和13-diene-15-oic酸。通过对2个降解产物和α的13C NMR谱的分析和赋值，通过13C NMR谱确定了其结构。-二乙酸茴香碱和甲基茴香碱。
In addition to methyl communate the hitherto unknown 3-acetoxylabda-8(20),13-diene-15-oic acid was isolated from the autumnal leaves of M. glyptostroboides. Its structure was determined by 13C NMR spectroscopy, aided by the analysis and assignment of the 13C NMR spectra of 2 degradation products as well as .alpha.-onocerine diacetate and of methyl communate.
